PS3 (5-6)-8: Students demonstrate an understanding of motion by…
8a using data or graphs to compare the relative speed of objects.
8b recognizing that a force is a push or a pull.
8c explaining that changes in speed or direction of motion are caused by forces.
PS3 (7-8)-8: Students demonstrate an understanding of motion by…
8a measuring distance and time for a moving object and using those values as well as the relationship s=d/t to calculate speed and graphically represent the data.
8b solving for any unknown in the expression s=d/t given values for the other two variables.
8c differentiating among speed, velocity and acceleration.
Students demonstrate an understanding of force (e.g., friction, gravitational, magnetic) by…
8d making and testing predictions on how unbalanced forces acting on objects change speed or direction of motion, or both.
